Google re-opened the invites for the Google+ social network of the short span of time in order to double the number of users during the initial trailing period.There is huge demand Many users are willing to join the new Facebook rival Google+, because they want to know the features of this social product from Google.But Google closed the invites last week and then briefly opened it again on last Wednesday.
The invite mechanism has now closed again, presumably after Google racked-up enough new users to double the population.
Last night engineering direct Dave Besbris posted on the Google+ site, explaining that the limited roll-out is to ensure that the network works properly and that bugs only affect a small amount of users.
He said: "I wanted to take a moment to explain why we’re growing the system slowly. First, we want to make sure our infrastructure scales so the service remains fast and reliable.
"Second, we want to ensure that bugs are fixed while there are still a relatively few people in the field trial.
"Things are going well with the systems right now so we feel comfortable enough to open up invites for a brief period.
"Our goal is to double the user base in the field trial. (Sorry, we’re not giving details about how many folks are in the field trial yet)."
"So, in a few minutes, we’ll open up invites again.We continue to throttle invites, so please don’t mass invite folks as it won’t work. If you invite a handful of your most important friends and family you’re much more likely to get these folks into our system."
Google has yet to reveal when a full public launch will take place.
